COVER-PLATE FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed September 7. 1905. Serial No. 277,351.

To all whom it may concern:

Be it known that I, RUssEL G. WOOD- WARD, a citizen of the United States, residing at Waukegan, in the county of Lake, State of Illinois, have invented certain new and useful Improvements in Cover-Plates for Sewing-Machines, of which the following is a description, reference being had to the accome panying drawing and to the letters and figures of reference marked thereon.

My invention relates to an improvement in sewing machines, and especially to the cover plate therefor, the object being to provide a construction of cover and cooperating parts whereby convenient means of access to the operating parts of the machine may be secured.

As herein shown, the invention is applied to an overseaming machine of the Union Special type, and the cover is in certain respects an improvement upon that shown in the application filed by Lansing Onderdonk, July 26th, 1904, Serial No. 218,192. It will be understood, however, that so far as the broad idea is concerned, I do not wish to be limited to any particular type of machine, nor toany particular construction of cover plate so long as it embodies the main feature of the invention as set up in the claims.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 represents a side view of the bed plate of a sewing machine, embodying the invention. Fig. 2 is a perspective view of the inner side of the cover plate and stripdiverting guide and Fig. 3 is a sectional view on line 33 of Fig. 2. tail view, showing the locking pin and the means for operating the same.

In these drawings, the hinged cover plate is shown at 38 and it is attached to the bed casting of the machine along its bottom edge by screws 39, and held in place at the top by spring pin 40, inserted in the top of the central bearing lug for the main shaft and registering with the hole 41 in the cover 38. This cover 38 carries on its outer face, a guide 42, for diverting the strip severed from the body fabric, towards the front of the machine and away from its operating parts. This divert ing guide is normally spring pressed forward,

Fig. 4 is a sectional dethe cover 38 by means of screws 45 passing through slots 46 in said cover.

The primary object of the present invention is to provide means whereby at the same time that the plate carrying the strip-diverting guide is moved to the right, to allow the cover to be swung in, it will operate the hold ing pin for the cover to release the same, so that by a single manipulation the strip-diverting guide may be swung to the right, the cover released and turned down to position to allow the working parts to be exposed. To this end, I have provided on the plate which carries the strip-diverting guide, an angle plate 50, secured to the plate by the screw 45, and having a finger piece 51, the upper arm of said plate 50, which is marked 52, having a beveled lower face at one end, so that as the plate 50 is slid to one side, the beveled face of the angle plate will bear against the spring pin 40, and force the same down to release the cover, which can then be swung down by means of said finger piece. This provides a simple and effective means for accomplishing the object aimed at.

While the invention is particularly applicable to the type of cover plate as above set forth, it will be understood that it may be applied to other types, so long as the gist of the invention is present, namely, the provision on the cover plate, of a device simultaneously adapted to actuate the cover, and

at the same tune to operate the locking device to allow said cover to be shifted to enable access to be gained to the interior of the machine.

Having thus described the invention, What I claim as new and desire to secure by Letters Patent, is

1. In a sewing machine, a cover plate attached to and supported by a stationary part of the machine frame and adapted to be moved to afiord access to the interior of the machine, means for locking the same in its closed position, and a single implement independent of the locking means adapted to be manipulated by the operator for operating the locking means and moving said cover plate upon its support; substantiallyas described.

2. In a sewing machine, a sectional cover plate attached to and supported by a stationary part of the machine frame, and

adapted to be moved upon its support, means for locking the cover plate in its closed position, means for moving a portion of said cover plate laterally and simultaneously operating the locking device; substantially as described.

3. A sectional cover plate for sewing machines, pivoted to the machine frame, means for locking the same in its closed position, means for slidingly supporting one portion of the cover on the other, and means for simultaneously moving said sliding portion and operating the locking means for said cover plate; substantially as described.

4. A hinged cover plate for sewing machines, a member carried by the machine frame and adapted to engage the cover plate when in closed position, a plate sliding on said cover plate, a handle on said sliding plate, and means carried by said handle,

whereby when the plate is moved, the said member is engaged or disengaged from the cover plate; substantially as described.

5. A hinged cover plate for sewing machines, adapted to engage holding means on the machine frame, a sliding plate on said cover plate carrying a diverting guide, an angle piece on said sliding plate having a handle and having an arm adapted in the movement of said sliding plate to come in contact with the holding means upon the cover plate and operate the same substantially as described.

In testimony whereof I afiiX my signature in presence of two witnesses.

RUSSEL G. WOODWARD.
